Osteoblastoma is a bone forming tumor with histological features highly similar to osteoid osteoma; the discrimination between the tumor types is based on size and growth pattern. The vast majority of osteoblastomas are benign but there is a group of so-called aggressive osteoblastomas that can be diagnostically challenging at the histopathological level. The genetic aberrations required for osteo

Popular Abstract in Swedish Enterohemorragisk Escherichia coli (EHEC) EHEC är mycket virulent för människor, det räcker med så få som 50-100 bakterier för att man ska bli infekterad och utveckla symtom. Varje år rapporteras ca 300-500 fall av EHEC smitta i Sverige. Den stam som oftast isoleras från patienter är E. coli O157:H7. Reservoarer för EHEC är idisslare och framförallt kor. Kor är nämligHemolytic uremic syndrome (HUS) is characterized by non-immune hemolytic anemia, thrombocytopenia and acute kidney failure. The most common form of HUS is associated with gastrointestinal Shiga toxin-producing enterohemorrhagic Escherichia coli (EHEC) infection. EHEC are non-invasive strains with Shiga toxin as the unique virulence factor. The aim of this study was to describe host-pathogen intera

One of the main ways in which in-between time-spaces are organised and materialised in the urban environment is through waiting places. In his article we point to the transformative potential of waiting places, their role as actors in an urban web, and discuss briefly their societal role in recent historical changes. Public waiting places are today increasingly becoming pre-programmed: connected t

FTIR study of the evolution of multivacancy-oxygen-related defects in the temperature range 100-350 degrees C in Czochralski-grown Si samples irradiated with different particles (10 MeV electrons and 5 MeV neutrons) has been carried out. Appearance of two absorption bands positioned at 833.4 and 842.4 cm(-1) has been found upon annealing of the divacancy related absorption band at 2767 cm(-1). The

The beta decay of five heavy, neutron-rich nuclei, Pt-203,Pt-204 and Ir200-202, has been investigated following relativistic cold fragmentation reactions of lead projectiles using the FRS + RISING setup at GSI. This paper reports on the study of the low-lying states in the decay daughter nuclei Au-203,Au-204 and Pt200-202. The characteristic gamma rays for each nucleus have been determined using b

Preclinical studies in mice suggest that the natural killer cell receptor NKp46 may be a new molecular target for delaying the progression of type 1 diabetes by interfering with unexpected natural killer cell-mediated recognition of pancreatic beta cells.

The objective is to investigate whether a silicon diode detector designed to measure the radiation levels in medical diagnostics also could be used as a dosemeter for people involved in the handling of a nuclear or radiological accident.

Individuals differ consistently in their behavioural reactions towards novel objects and new situations. Reaction to novelty is one part of a suit of individually consistent behaviours called coping strategies or personalities and is often summarised as bold or shy behaviour. Coping strategies could be particularly important for migrating birds exposed to novel environments on their journeys. We c

Accurate accelerator mass spectrometry (AMS) measurements rely on standards with well-known isotopic ratios. For radiocarbon measurements, a number of standards with different properties are commercially available, of which the IAEA-C6 sucrose standard with a 14C value of 150.61 pMC is the most active. When analyzing biological samples resulting from studies using 14C-labeled substances, the activ

Ecological interactions between microparasite populations in the same host are an important source of selection on pathogen traits such as virulence and drug resistance. In the rodent malaria model Plasmodium chabaudi in laboratory mice, parasites that are more virulent can competitively suppress less virulent parasites in mixed infections. There is evidence that some of this suppression is due to

Introduction: Biomarkers of brain damage and head injury are potentially useful tools in the management of afflicted patients. Particularly S100B has received much attention and has been adapted into clinical guidelines. Alcohol intoxication and higher age (65 years and over) have been used as risk factors for serious complications following head injury. The effect of these factors on S100B levels

The participation of transnational actors in global policymaking is increasingly seen as a means to democratize global governance. Drawing on alternative theories of democracy and existing empirical evidence, we assess the promises and pitfalls of this vision. We explore how the structuring and operation of international institutions, public-private partnerships, and transnational actors themselve

We present a theoretical investigation of the hyperfine structure of the 5s5d D-3(2)-5s4f F-3(2,3)0 transitions in In II. Earlier work has failed in determining hyperfine constants for the upper levels of these transitions. We show that this is due to strong off-diagonal hyperfine interaction, which not only changes the position of the individual hyperfine lines but also introduces large intensity

Introduction: Interatrial frequency gradient is used to guide catheter ablation of atrial fibrillation (AF) but reliable tools for its non-invasive estimation are lacking. We present a patient with dissociated left and right atrial rhythms that allows identification of sum face ECG leads that closely reflect left atrial activity. Methods: 12-lead ECG was recorded simultaneously with electrograms f

Evidence is accumulating that one of the strongest predictors of retinopathy of prematurity (ROP), in addition to low gestational age, is poor weight gain during the first weeks of life. In infants born preterm, the retina is not fully vascularised. The more premature the child, the larger is the avascular area. In response to hypoxia, vascular endothelial growth factor (VEGF) is secreted. For app

Triglycerides are transported in plasma by specific triglyceride-rich lipoproteins; in epidemiological studies, increased triglyceride levels correlate with higher risk for coronary artery disease (CAD). However, it is unclear whether this association reflects causal processes. We used 185 common variants recently mapped for plasma lipids (P < 5 x 10(-8) for each) to examine the role of triglyceri

Although octupoles, decapoles, and longitudinal gradient bending magnets (LGB) have been studied for many years, they are not usually included in light source lattices. They can, however, be beneficial in order to realize ultralow emittance and attain sufficient dynamic aperture. We present methods for achieving ultralow emittance and discuss optimization of the nonlinear dynamics with multipoles.

We present first measurements of charged and neutral particle-flow correlations in pp collisions using the ATLAS calorimeters. Data were collected in 2009 and 2010 at centre-of-mass energies of 900 GeV and 7 TeV. Events were selected using a minimum-bias trigger which required a charged particle in scintillation counters on either side of the interaction point. Particle flows, sensitive to the und

We present a comparative study of xanthorhodopsin, a proton pump with the carotenoid salinixanthin serving as an antenna, and the closely related bacteriorhodopsin. Upon excitation of retinal, xanthorhodopsin exhibits a wavy transient absorption pattern in the region between 470 and 540 nm. We interpret this signal as due to electrochromic effect of the transient electric field of excited retinal
